برهن

Q., or, as some say, Q. Q., 1.Q. 1 بَرْهَنَ He adduced, (T, Z, Msb,) or established, (S, K, and Ham p. 7,) the بُرْهَان, (T, Z, Msb, K,) i. e. the evidence or proof [&c.]; (T, S, Msb, &c.;) or he adduced his evidence or proof [&c.]; (T, Msb;) عَلَيْهِ [against him, or it, or (as in اِسْتَدَلَّ عَلَيْهِ) of it], (S, K, and Ham p. 7,) and لَهُ [to him, or for him]: (Ham ubi suprà:) but this verb is said by Az and Z, on the authority of IAar, to be post-classical; the correct word, they say, being أَبْرَهَ: (Msb:) this they assert on the ground of the opinion that بُرْهَانٌ [q. v.] is of the measure فُعْلَانٌ; but J holds the ن to be a radical. (TA.) بُرْهَانٌ An evidence, or a proof: (T, S, Msb, K, and Ham p. 7:) and a demonstration; i. e. the manifestation of an evidence or proof: (Msb:) or a decisive and manifest evidence or proof: (TA:) or the firmest, strongest, or most valid, evidence or proof; which is such as ever necessarily implies truth, or veracity, as its consequence, or concomitant; for evidences, or proofs, are of five sorts; whereof this is one; another is that which ever necessarily implies falsity, or falsehood, as its consequence, or concomitant; another, that which is nearer to truth, or veracity; another, that which is nearer to falsity, or falsehood; and another, that which is intermediate between these two: (Er-Rághib, TA:) [pl. بَرَاهِينُ:] some say that the ن in this word is augmentative; (Msb, and Ham p. 7;) that it is of the measure فُعْلَانٌ, from البره [app. البَرْهُ] signifying the “act of cutting:” (Ham ubi suprà:) others, that it is radical: Az mentions both of these opinions: J confines himself to the latter opinion: Z, to the former, saying, on the authority of IAar, that the word is derived from بَرَهْرَهَةٌ, meaning “white,” [or “fair in complexion,”] applied to a girl: (Msb:) Abu-l-Fet-h [i. e. IJ] says that he holds it to be of the measure فُعْلَالٌ, like قُرْطَاسٌ and قُرْنَاسٌ, the ن not being augmentative, as is shown by the verb above mentioned: (Ham ubi suprà:) but [it has been stated above that] this verb is said, on the authority of IAar, to be post-classical.
